I think another reason PPSSPP can run games faster is because it can basically HLE everything as user mode applications. It doesn't have to do any of the weird things required to get PS2 games running. PSP is also significantly weaker. Also, PPSSPP is newer and has less clutter to it.
Don't quote me on it as I'm not technically minded, but I'm pretty sure emulating whatever the PSP processor is (MIPS? ARM?) is probably a lot easier than emulating the assortment of non-standard processors the PS2 has.
